Can you add/do the following...?

1) You will need certain options installed beforehand, i think its doable but expensive. Someone else should advise you here as i don't have this feature.
2) Not sure if its codeable without "hardware". My S-tronic has automatic handbrake release and hill assist.
3) Yes but you need Kessy i think, the sensors in the door handles and perhaps the advanced key. Not exactly sure. One of these things is certain.
4) Yes but you need electric seats (i think its called Comfort Entry)
5) Don't think the glovebox has any music inputs except 2x SD Cards and 1x CD. The AUX is located under the handrest in centre console. Not sure if its standard included.
6) Should be able with a USB cable if you have Android Auto installed. Expensive retrofit.
7) Well you can use your car as a wifi hotspot, you can update mmi stuff via wifi. You can connect your non 3g/4g devices to it and connect to the hotspot (sim card needed inside or if u use a device with 3g/4g to share cellular). So basically you can share your mobile devices/sim cards cellular data via audis wifi hotspot to anyone nearby.

EDIT: Just realized you're talking about 2020 a4...Things might be different to my 2016

I can answer a few of those as I have been learning the ways of the 2020 car this month.
A lot as I have learn depends on spec but 2 things I can help with

Do you have auto handbrake when you press the brake hard as you stop ( green p appears on dash )

If so when you stop the car to park press the stop/star button and the car will automatically apply handbrake and park mode.

As for music , any phone connected via USB, or a USB stick inserted in the socket next to the 12v from socket plays music.
In addition so will your phone which can be hard cabled via either the USB c under the arm rest or the front socket.

Seat depends on you having electric seats and yes obd11 can add easy access feature.

1. Nearest you can really get is a Siri shortcut (not sure on android) And only lock / unlock. It’s not the fastest either.
3. Yes with Vcds / obdeleven. (Auto unlock)
4. If you have electric seats.
5. That’s correct.
6. Yes
7. WiFi hotspot if you purchase a cubic telecom package.
